Three more executives are leaving the company: Qi Lu, executive vice president of engineering for search and advertising technology; Brad Garlinghouse, senior vice president of communications and community; and Vish Makhijani, senior vice president of search, TechCrunch reported Thursday.

, in which he complained, "We want to do everything and be everything--to everyone...The result: a thin layer of investment spread across everything we do and thus we focus on nothing in particular."

The pressure has to be strong for Makhijani, too. Yahoo is interested in search, but in the last year, search queries performed at Yahoo in May declined 13.8 percent to 1.33 billion while Google's increased to 4.65 billion, according to statistics released Thursday by Nielsen Online. And third-place Microsoft, whose search queries increased 72 percent to 1.04 billion, is trying to poach Yahoo search employees.

"We have a deep and talented management team across all areas of the company. Our successful implementation of our core strategies and the timely rollout of key products this year testifies to the effectiveness of our team, and we continue to recruit outstanding talent. Yahoo continues to be a leader in our industry and remains a unique, exciting, and important place to work even as we experience the attrition that's to be expected in the Internet industry."

I have to wonder: Is this the level at which attrition is "expected"?

Update 5:07 p.m. PDT: I've confirmed all three departures from multiple sources familiar with the situation.

And there's more: Yahoo plans a major reorganization, potentially to be announced as soon as next week, one source said. This change will be of much bigger magnitude than the rejiggerings of recent quarters.

"It's definitely not a shuffle," the source said. But while some have called for the ouster of Chief Executive Jerry Yang, the change won't affect him or President Susan Decker, apparently. And it likely won't involve layoffs.

One factor contributing to some of the executive departures is dissatisfaction with how they'd end up after the reorganization, the source said. Another is what amounted to the choice of recommitting to Yahoo or moving on.

But one source within the company had a more skeptical view of the reorganization, believing it a forced reaction to executive departures rather than the cause.

"You can see that Jerry does not have the support of the leadership inside Yahoo," the source said.
